Bolodon

Bolodon was a mammal from the Lower Cretaceous of Europe, (and perhaps the Upper Jurassic of North America). It was a member of the extinct order of Multituberculata, and lived at the same time as dinosaurs.

(For the technically minded, suborder "Plagiaulacida", family Plagiaulacidae.)

Genus: Bolodon Owen R, 1871
Aka?: Plioprion
Remarks: Material has also been reported from the Upper Jurassic Morrison Formation[?] of North America. I haven't yet been able to find confirmation or details.
Some authors ascribe this genus to its own family, Bolodontidae.

Species: Bolodon crassidens
Place: Durlston Bay, Dorset & Galve?
Country: England & Spain?
Age: Lower Cretaceous
Remarks: The Spanish possibility is contained in a webpage by John H Burkitt, but I haven't found any confirmation elsewhere.

Remarks: This is very possibly not part of the genus: "?new genus to be erected for 'Bolodon' elongatus," (Kielan-Jaworowska & Hurum, 2001, p.414).

Species: Bolodon minor
Aka: Plioprion minor
Place: Durlston Bay, Dorset
Country: England
Age: Lower Cretaceous
Remarks: Plioprion Cope, 1884 is probably synonymous with Bolodon. I've no idea if this species is still considered valid.
